Product Details

Global Parts 4811904 is an HVAC A/C accumulator with hose assembly for rear air conditioning systems. In A/C plumbing, suction hoses carry low-side refrigerant from the compressor to the evaporator, while discharge lines move high-side refrigerant from the compressor to the condenser. This assembly is used in rear AC configurations where the hose routing and accumulator function must match the vehicle’s original layout. It cross-references Four Seasons 83045 and 83046 for the same application.
